PEG-5 BERTHOLLETIA EXCELSA SEED OIL GLYCERYL ESTERS.

Valuable / SKIN CONDITIONING

This ingredient is a PEGylated ester derived from Brazil nut oil, acting primarily as a skin-conditioning agent and emollient. It significantly enhances skin hydration and supports barrier function, delivering antioxidant benefits for improved skin texture and elasticity.

Summary

Skin Conditioning Emollient Surfactant

Science

Mechanism of Action

Functioning as an emollient and skin conditioner, PEG-5 BERTHOLLETIA EXCELSA SEED OIL GLYCERYL ESTERS provides a protective barrier to reduce transepidermal water loss. Its Brazil nut oil component is rich in oleic and linoleic acids, which bolster the skin's natural barrier and contribute to sustained moisturization. Furthermore, the oil's selenium and Vitamin E content offers antioxidant defense against free radicals, while the PEG component actively binds to water molecules, ensuring prolonged hydration and mitigating moisture evaporation from the skin. It also possesses mild surfactant properties.

Stability

While a specific optimal pH range for stability is not available, as a non-ionic PEGylated ingredient, it is readily compatible with hydrophilic systems and can be incorporated into water-based skincare formulations.

Conflicts

  • Not recommended for application on damaged skin due to potential irritation.
  • Increased irritation risk when formulated with other known problematic ingredients.
  • Typically excluded from organic or natural certified cosmetic formulations due to the ethoxylation process and potential impurities like ethylene oxide.

Safety

Safety Profile

CIR Status
Safe with restrictions
Sensitization risk Low

The CIR Expert Panel considers PEGylated oils, including chemically similar compounds, safe for cosmetic use when formulated to be non-irritating. The Brazil nut oil itself is independently deemed safe. Manufacturers are advised to purify PEG derivatives to remove impurities like ethylene oxide and 1,4-dioxane. Although topical, the FDA mandates allergen labeling for Brazil nuts in food. This ingredient should not be used on compromised skin. Certain ethical sourcing standards may classify ethoxylated ingredients as 'Muy Dudoso' due to concerns regarding carcinogenic ethylene oxide.
